SPECIFICATION forming part of Letters Patent No. 786,290, date'cl April4, 1905.

Application led November 23,1903. Serial No. 182,379.

To all whom, t may concern.:

Be it known that we, WILLIAM Hossn and ROBERT MoEwEN, citizens of theUnited States, residing' at Nashville, in the county of Davidson andState of Tennessee, have invented certain new and useful Improvements inRoundabouts, of which the following' is a speciication.

Our invention relates to roundabouts or merry-go-rounds in which aseries of rotatable platforms carrying various devices or figures aresupported from a main spindle or shaft and operated from any suitablesource of power.

The objects of the device are to so construct it that it may be easilyand cheaply manufactured, can be readily assembled, and Will require buta small amount of power for its operation.

In the drawings forming a part of this speciication, and in which likesymbols of reference represent corresponding parts in the several views,Figure 1 is a vertical sectional view of the device; Fig. 2, a verticalsection of the shaft and spiders connected to the same, and Fig. 3 asectional plan View.

1 and 1u represent tight and loose pulleys on shaft 2 for driving thedevice; 3 and 4, pedestals in which shaft2 is journaled; 5, abevelpinion keyed to shaft 2; 6, agear meshing' with pinion said gearbeing cast or forned with four pockets 6 to receive a shaft 9 and lugsformed on thc same.

7 is a main bed-plate turned inside for rollers 17, turned on top forsteel plate 10, and beveled out or recessed at 10, so as to form abearing for shaft 2 to run in. We have also designated the other platesby the numeral 10.

8 represents steel balls to reduce the friction of the parts, the samerunning on steel plates 10.

9 is the main shaft turned for rollers 17 18 l19 and cast or formed withfour lugs 191 to rest in pockets or recesses 6 in gear 6. The shaft 9also has four lugs 2Ou for spiders 12 and 14, said lugs supportingspiders 12 and 1,4 and acting as a key to lock the spiders to the shaft.

26 is a band supported upon lugs 21, formed on top of shaft 9.

11 and 13 are cast-iron spiders cast in one piece, turned inside forrollers 18 and 19, and turned on top and bottom for steel plates 10. Thespiders are then split, so as to go around shaft 9 and be boltedtogether by eight bolts. Spider 11 is shown constructed to receivefourteen beams for outside horses and spider 13 constructed to receivefourteen beams for inside horses and having also ratchet-teeth cast withthe said spiders.

12 is a cast-iron spider cast with four pockets 22a to rest on shaft 9to act as key for same, turned on top and bottom for steel plates 10,and then split and placed around shaft 9 and bolted together. Thisspider is shown constructed to receive fourteen beams for revolvingfloor 33.

14 is a cast-iron spider cast in one piece and not split, as the same isunnecessary, with four pockets 14*1 to rest on shaft 9 and act as keyfor same. This spider usually receives twelve beams 24 for revolvingfloor 25 and seat 20.

15 represents steel dogs to work in ratchetteeth in spiders 11 and 13and bolted to shaft 9 by bolts 16. These dogs are held in engagementwith the ratchet-teeth by springs 16a. Rollers 17, 18, and 19 runbetween shaft 9 and bed-plate 7- and spiders 11 and 13. Rollers 18 and19 rest on collars 23a, formed on shaft 9.

2O is a seat around shaft 9, the saine formed of any preferred design,or it may be, if desired, a music-box. Y

21, 22, and 23 are I-beams to be bolfd or clamped to spiders 11, 12, and13.

25 is a Wooden iioor laid on beams 24.

26 is a cast-iron band to fit shaft 9, with four holes to receivebrace-rods 27, and 28 are turnbuckles to adjust and steady shaft 9.

29'represents steel channel-irons bolted to beams 21, 22, and 23 toseparate and steady beams that support horses; 30, iron angleplates, oneon either side, to bolt beams 21 22 to 35 and 23 to 31; 31, steelI-beams at right angles to beams 23 for inside horses, and 21 at rightangles to 31a for outside horses; 32, steel channel-irons bent to fillup opening between beams 31, and 32a channel-irons for beams 31a.

IOO

33 is a wooden floor laid on cast-iron angleplates 34, said angle-plates34 being bolted to beams 35.

36 is a wooden fioor around outside horses.

The operation of the device will be apparent from the foregoing. Powerbeing applied from any source to pulley 1, the shaft 2 is rotated andwith it the shaft 9 and the frame of the device carried thereby. Theengagement of the pawls in the ratchets of the spiders Il and 13 carriessaid members around and with them the other parts. sustained by shaft 9.When the loose pulley has received the band, power is of course eut offfrom the device and the pawls working in the ratchets permit a gradualstoppage of the machine, thus preventing any jarring of the parts.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. In a roundabout, a main shaft, platforms driven thereby, asupporting-base, a gearwheel revolubly mounted on the base, pockets insaid gear-wheel, lugs on the shaft received in said pockets, a pinionmeshing with the gear-wheel, and means for imparting motion to thepinion to operate the shaft.

2. In a roundabout, a main shaft, detachable spiders connected te thesame, interlocking means between the spiders and the shaft, each spiderbeing revoluble independently of the adjoining spider, beams carried bythe spiders, and means for connecting the beams to the spiders.

3. In a device of the character described, a main shaft, separablespiders, means for locking some of said spiders to the shaft, means forrevolubly connecting the other of said spiders to the shaft, agear-wheel connected with the base of said shaft, a main base supportingthe gear-wheel, and means for driving the gear-wheel.

4. In a device of the character described, a main shaft, a gear-wheelconnected to the base of the same, a bed-plate supporting thegear-wheel, means for driving said gearwheel, spiders detachablyconnected to the main shaft, flanges formed on the main shaft, rollerslocated between the main shaft and spiders and adapted to ride upon saidHanges, and a pawl-and-ratehet mechanism between the main shaft andspiders.

5. In a roundabout, a main shaft, a gearwheel connected to the base ofthe same, a bed-plate supporting' the gear-wheel. a hori- Zontal shaftjournaled in the bed-plate, a pinion on the horizontal shaft engagingthe gear-wheel of the main shaft, separable spiders, fianges on the mainshaft receiving and locking some of the spiders thereto, ratchetmechanism between the shaft and other of said spiders, roller-supportingflanges also on the main shaft, and rollers on said flanges.

6. In a roundabout, a main shaft, a gearwheel connected to the same, abed-plate supporting the gear-wheel, a horizontal shaft carrying apinion in mesh with said gear, spiders detaehably connected to the mainshaft, supporting-beams detachabl y connected tothe spiders, some ofsaid bea-ms adapted to carry figures and others platforms, rollers onsaid fianges, ratchets on the figure-carrying spiders, pawls upon themain shaft to engage the ratchets of the spiders, tracks formed betweenthe various spiders, and antifrictionballs on said tracks.

In testimony whereof we afhX our signatures in presence of twowitnesses.

WILLIAM Hesse. ROBERT MCRWRN.
